SPECIFICATION forming part of Letters VPatent No. 413,355, dated October22, 1889.

Application filed October 19, 1887. v Serial No. 252,861. (No model.)

To all whom it may concern:

Be it known that l, JAMES VATSON, a citizen of the United States,residing at Marinette, in the county of Marinette and State ofWisconsin, have invented a certain new and useful Improvement in SashLocks and Stops, which is fully set forth in the followingspecification, reference being had to the accompanying drawings, inwhich- Figure l is a. face view of a portion of a window and casinghaving my improvement applied thereto; Fig. 2, a similar detail viewhaving a portion of the sash-rail and casing broken away to show theconstruction; Fig.

3, an edge view of part of the sash partly broken away and with myimprovement attached; Fig. 4, a sectional View taken on the line l l ofFig. 3; Fig. 5, an elevation of the face plate or strip detached; Fig.6, a view similar to Fig. 2 and showing a modified form of the device,and Fig. 7 a sectional view taken on the line 2 2 of Fig. 6. Figs. 2 to7, inclusiveare on the same scale with respect to each other, but on alarger scale with respect to Fig. l.

Like letters refer to like parts in all the figures of the drawings.

My invention relates to sash locks and stops, and has for its object toprovide a device of this description which shall possess various pointsof superiority, both in construction and operation, over the devices forsimilar purposes heretofore employed, and which shall be cheap andsimple in construction and effective in operation.

Tothese ends my invention consists in certain novel features, which Iwill now proceed to describe, and will then particularly point out inthe claims.

In Figs. l todof the drawings l have shown my improved lock asconstructed and organized as a blind or mortise lock. In `thisconstruction I form within the side face of the side rail A of thewindow-sash, which abutsV against the casing A', a inortise d of asuitable size and shape to receive and conceal the lock.

means of which the lock is secured to the sashi rail A. The lugs bextend beyond the body B, and between them and parallel to the body isarranged' a face-plate B,which is connected to the body B by means ofthree rivets or screws C, C', and C2. the body B and face-plate B', andin this space are arranged the inner ends ofthe pivoted stop-arms D andD ,the rivet C forming the pivot of the arm D, and 'the rivet C foriningthe pivot of the arm D. These arms eX- tend, respectively, upward anddownward from the body or seat B, andare thrust normally outward bysuitable springs, which springs are preferably very light or weak, so asto offer as. little resistance as possible to the operation of thestoparms, in the manner hereinafter described. rlhese springs maybe ofany suitable construction and arrangement for their purpose; butpreferably I provide for each arm a coil-spring d, which restsin asuitable recess h2 in the corresponding lug b of the body portion B, andwhich bears against the arm, which latter is provided with a projectiond', which enters the center of the coil and prevents displacementthereof.

l represents the operating lever or arm, which is preferably pivoted onthe rivet C2 between the body B and face-plate B. This lever or arm isprovided on each-side of its pivot with a toe or projection e, whichengages a corresponding notch or indentation d2 of the arm D or D', asthe case lnay be. It will thus be seen that the operating arm or lever Eengages both of the stop-arms, these latter being held in engagementwith it by means of their springs. The lever E is provided with a knobor handle E', which extendsup through -a slot f in the rail A, the saidknob or handle resting. in a recess F in the inner face of the said railand being flush with or below the level of the surface o f the saidface. Preferably an escutcheon F of suitable shape to lit within therecess F, and

suitable manner, is employed to give this portion of the lock, which isthe only visible portion when the lock is in position, a neat andiinished appearance;

The face of the window-casing A opposite to the rail A, which carriesthe lock, is provided with a series of recesses d', with which thestop-ar1ns D and D may engage, as here- Aspace is left between,

secured to the rail by screws f or in any other.

ICO

inafter set forth. Each recess a has of course an upper wall a2 and alower wall a3, each of these walls forming astop with which one of thearms engages. Preferably I apply to the face of the casing A afacing-strip G, constructed as shown more particularly in Figs. 2 and 5of the drawings. This facing-strip is of metal-preferably ironand isprovided with apertures g, corresponding in size to the recesses a inthe casing, and having ianges g', which rest against the end walls a2and as of the recesses a to give the same a metallic facing and preventwear thereof.

The form of lock just described is, ashereinbefore stated, amortise-lock,whichis iush with the inner face of the sash-rail and theonly visible portions of which are the knob or handle E and theescutcheon F. rlliis form of lock may be applied to the upper sash aswell as to the lower, since it does not project beyond the inner face ofthe sashrail. The lock may, however, be constructed and organized as asurface-lock, and I have so shown it in Figs. 6 and 7 of the drawings.In this construction the body B comprises in itself both the seat andface-plate, having a suitable aperture'cast in or otherwise formedthrough the same to receive the stop-arms D and D and the operating armor lever E. The lugs Z9 are in this case arranged in the same plane withthe body B and not at right angles thereto, so that the lock may beattached directly to the inner face of the sashrail. A suitable cap orcasing B2 is provided, which coversY the body and the adjacent por tionsof the stop-arms and lever as well as the springs d and protects thesame from injury. This cap is secured by the screws h or in any othersuitable manner. The .onstruction and arrangement is in the main thesame as that already described in referring to the mortise-lock, thechanges being merely such as are necessary to adapt the lock to itschanged situation.

The operation of my improved lock and stop is as follows: It will beobserved that in its normal position the arms D and D engage,respectively, wit-h the upper wall a2 and lower wall a3 of therespect-ive recesses a opposite which they happen to be, and thusprevent any movement of the sash in either direction. When the sash isclosed, it cannot of course be opened from the outside, since the lockis not accessible from that side. Vhen it is desired to raise thewindow, the knob or handle E is pressed upward, when the upper stop-armD will be withdrawn within the mortise or clear of the recess with whichit is engaged, and the sash may be raised to any desired extent. Duringthis upward movement of the sash the lower stoparm D will, by itsengagement with the lower walls a3 of the recesses a', hbld the sash upand prevent its descent when the sash is raised. Then it is desired tolower the sash, the knob or handle E is depressed, when the lowerstop-arm D is withdrawn and the sash may be lowered, as desired. In anyposition in which the sash may be left the arms D and D eifectuallyprevent any movement of the sash in either direction until the stop-armsare actuated as desired by means of the knob E. It will be observed thatthe said knob or handle is moved in the direction in which it is desiredto move the sash, thereby econo- Inizing strength and time, since thesame force which is applied to move the knob serves also to move thesash. It will also be observed that the stop-arms, although they arecontrolled by the operating' arm or lever, being held in contact withthe same by their springs, are capable of yielding independently of thesaid stop-arm and of each other, and are thereforeindependent armscontrolled by the said operating-lever.

Various modifications in the details of construction may be made withoutdeparting from the principle of my invention; and I therefore do notwish to be understood as limiting myself to the precise detailshereinbefore described, and shown in the drawings.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, isp l. The combination, with the recessedcasing, of the sash-rail provided with a mortise, and the lock arrangedwithin said mortise and consisting of al body portion having pivotedthereto the independent spring controlled stop-arms extending,respectively, upward and downward, and the operating-lever pivoted tothe body, engaging the stop-arms and provided with a knob or handleextending through a slot in the sash-rail and flush with the same,substantially as and for the purposes specified.

2. In a sash-lock, the combination,with the independentspring-controlled stop-armspiv-4 oted at their inner ends, and eachprovided with a notch or indentation d2, of the operating-lever E,provided with the toes e to engage the said notches, substantially asand for the purposes specified.

3. The combination, with the body B, liaving lugs b with recesses b2, ofthe pivoted arms D D', and the springs d, arranged in said recesses andbearing against the said arms, substantially as and for the purposesspecified.
